    Genetic analysis of the Arabidopsis TIR1/AFB auxin receptors reveals both overlapping and specialized functions

    Michael J Prigge et al.
    Genetic analyses reveal that the TIR1/AFB auxin receptors have broadly overlapping functions throughout plant development, but that the AFB1 receptor has a specialized role in a rapid auxin response.

    Bacteria: How Legionella defend their turf

    Elisa D Hughes, Michele S Swanson
    Communities of bacteria that cause Legionnaire’s disease repel other bacteria by secreting an acid called HGA.

    DNA-PK is a DNA sensor for IRF-3-dependent innate immunity

    Brian J Ferguson et al.
    Experiments in mice have shown than an enzyme that repairs broken DNA inside the nucleus also has a central role in the innate immune system because it is able to detect foreign DNA outside the nucleus.

    TIR1/AFB-Aux/IAA auxin perception mediates rapid cell wall acidification and growth of Arabidopsis hypocotyls

    Matyáš Fendrych et al.
    The nuclear pathway for auxin perception is responsible for the rapid auxin-induced cell wall acidification and growth of aerial organs of plants.

    Ribosome biogenesis restricts innate immune responses to virus infection and DNA

    Christopher Bianco, Ian Mohr
    Ribosome production is unexpectedly integrated into innate cell-intrinsic responses that regulate double strand DNA-sensing and inflammatory cytokine induction in infected and uninfected cells.

    Cellular encoding of Cy dyes for single-molecule imaging

    Lilia Leisle et al.
    Cyanine fluorophores are encoded as non-canonical amino acids to produce functional proteins in cell-free translation systems and live cells for single-molecule imaging.

    Myosin motors fragment and compact membrane-bound actin filaments

    Sven K Vogel et al.
    A combination of single-molecule imaging and an in vitro model of the cell cortex has allowed the interactions between actin filaments and filaments made of myosin II to be studied in detail.

    Recognition of tumor cells by Dectin-1 orchestrates innate immune cells for anti-tumor responses

    Shiho Chiba et al.
    An immune system pattern recognition receptor potentiates anti-tumor innate immune responses, offering new insight into anti-tumor activity of the innate immune system.

    ParB dynamics and the critical role of the CTD in DNA condensation unveiled by combined force-fluorescence measurements

    Julene Madariaga-Marcos et al.
    A single-molecule biophysical approach reveals that the C-terminal domain of ParB blocks ParB network formation by heterodimerization with the full-length protein, which remains bound to the DNA.

    Side-binding proteins modulate actin filament dynamics

    Alvaro H Crevenna et al.
    The kinetics of actin polymerization are strongly influenced by the binding of proteins to the lateral filament surface.
